A cigarette lighter is a small device used to create a flame for lighting cigarettes, cigars, or other items. It typically consists of a fuel reservoir, a spark mechanism, and a nozzle. Lighters can be refillable or disposable and are commonly made from materials like metal or plastic. There are various types of cigarette lighters, including butane lighters, electric lighters, and match lighters. Each type operates differently, but all serve the same basic purpose of providing a portable source of fire. Safety features are often included to prevent accidental ignition.
